Abstract: 149,000. Grunert, K., and Schreiner, K. E. M., (representative of Schreiner, L. P. E.). Jan. 11, 1916, [Convention date]. Liquids and vapours, treating with. - To fix and wash out fabrics that have been saturated with lye for the purpose of mercerizing, the stretched fabric enters at B into a cold rinsing- bath in a tank x, divided into compartments and provided with a cooling-device whereby some of the lye is removed, then the fabric is led around stretching- rollers I, II and between rollers a, b into a steam chamber A, where it is stretched by a roller III and fixed by the steam, after which it passes between pressing-rollers b, c direct into the cold bath, without coming into contact with external air, and is sprayed by water splashed by a beater p. Afterwards the fabric passes to and from the steam chamber, as shown, over guide-reels l, m, and finally leaves the apparatus at C. Means for removing condensed steam containing lye from the steam chamber are described. The steam chamber is separated from the cold bath by a tight-fitting wall of pressing-rollers a - - i mounted on a frame k and pressed tightly against the sides thereof, the end rollers bearing against packing-strips q, as shown. The steam chamber is closed by a hood o, which is water-sealed at p and can be raised, the cooling and rinsing bath being simultaneously lowered by means of a handwheel y and toothed racks and bars, the apparatus being thus opened and the pressing-rollers exposed to view. In the highest position of the rinsing-bath, the two side faces of the frame k and also the rollers b, d, f, h dip into the tank, to that the cavities between the rollers containing the beaters n can be shut off from the external air. The steam is introduced by pipes s, t provided with gutters u, v to collect condensed steam &c., and water can be introduced into the steam chamber by pipes z so as to cool the fabric &c. before opening the apparatus &c. When stretching breadthways or breadthways and lengthways, rollers I, II, III, which stretch the fabric laterally, are used; or these rollers may be replaced by guide-reels, and the squeezing-rollers be arranged to cause lengthways stretching of the fabric under treatment. According to the Specification as open to inspection under Sect. 91 (3) (a) the apparatus may be used in connexion with bleaching and sulphur or vat dyeing, and other steam-tight closing- devices for the entrance and exit of the fabric, such as rotatable flaps or valves, or troughs, or a water seal, may be employed.

IPC: G01M3/28
Filed: 1931-07-22
Abstract: 369,119. Locating leakages in oilfilled cables. SOC. ITALIANA PIRELLI, 21, Via Fabio Filzi, Milan, Italy. July 22, 1931, No. 20983. Convention date, April 15. [Class 99 (ii).] A leakage of oil through a hole in the lead sheath of one of three parallel cables 1, 2, 3 constituting a line is located by connecting the leaky cable 1 say to one of the sound cables 2 by a connection m at the cable joints A<1>, A<11> respectively, and then connecting oil reservoirs S<1>, S<11> to the other ends of the said cables at the joints A<1>o, A<11>o. The position of the leak P is determined by maintaining an equal level of oil in the two reservoirs, noting the quantities Q1, Q2 flowing from each in a definite time, and then substituting in the formula where L, x respectively are the lengths of the two cables and the distance of the leak from the joint A<1>. Variations in the volume of oil in the reservoirs due to variations in temperature during testing are compensated for by connecting a reservoir S<111> to the third cable 3. Several devices are described for maintaining a constant level of oil in the reservoirs. Specifications 255,033 and 268,27], [both in Class 38 (i), Electric couplings &c.], are referred to.

Title: Multiplex pulse transmission system
IPC: H04J3/00
Filed: 1964-05-21
Abstract: 1,071,392. Multiplex pulse signalling. PRECISION MECANIQUE LABINAL. May 21, 1964 [May 22, 1963; March 20, 1964], No. 21070/64. Addition to 1,053,492. Heading H4L. The multiplex pulse transmission system of the parent Specification wherein control signals are represented by the time interval between a reference pulse and a signal pulse is modified in that the pulses consist of, and are identified by, stepwise variations in the repetition frequency of short pulses of oscillations of constant frequency, the signal pulse of each channel having its own distinctive variation. At the transmitter periodic reference pulses (R), Fig. 1 (not shown), and control pulses (1 and 2) whose leading edges are coincident with (R) and trailing edges represent the analogue values to be transmitted are produced, the trailing edges being converted into pulses (6, 7) correspondingly time spaced from the reference pulses (R). Each of the pulses (R, 6 and 7) consists of a stepwise variation in the quenching frequency of pulses of high frequency oscillations, pulse (R) being characterized by quench frequencies appearing in the order (# B , # C , # A ), pulse (7) by quench frequencies (# C , # A , # B ) and pulse (6) by quench frequencies (# A , # c , # B ), Figs. 3 to 5 (not shown). A further sequence (# B , # A , # C ) is used for discrete signals. The analogue control signals are supplied to modulators 16, 17, Fig. 6 and the discrete signal is controlled by switch 18, the respective outputs being supplied to a logic unit 19 supplied with reference pulses from generator 20 and controlling gates 25a, 25b, 25c. The three quench frequencies are generated by crystal controlled oscillators 21 &c., converted into rectangular waves by the clippers 24 and supplied to the respective gates 25a, 25b, 25c. Under the control of the input signals the unit 19 opens the appropriate gates and operates a selector 13 so that pulses of R.F. from oscillator 10 at the quench frequencies representing the pulses R, 6 and 7 are transmitted via power amplifier 14. A similar selector 13a and power amplifier 14a provides diversity transmission. The receiver, Fig. 7 (not shown), is provided with three filters 36a, 36b, 36c, tuned to the respective quench frequencies, following the demodulator 35, which are connected to a logic unit 38 whose outputs are connected to load circuits 39, 40, 41. An anti-jamming device 42 controlled by the logic unit is connected to the outputs 39, 40. In a modified transmitter, Fig. 8 (not shown), a master switch (48) controls gates (45, 46, 47) in the input circuits so that only one gate may be opened at a time to prevent overlap of signals and is arranged so that the analogue control signal gates are opened alternately when the two input signals are coincident.

Abstract: 720,169. Automatic-feed weighers. HAVER, E., and HAVER, F., [trading as HAVER & E., BOECKER, C.]. Sept. 10, 1951, [Nov. 9, 1950; Feb. 14, 1951], No. 21263/51. Class 143. In an automatic valve-sack filling and weighing machine in which the sack 6 is supported on a saddle 12 pivotally mounted at 13 on the frame 9 of sack-stool 8 having a part cylindrical vessel 10 for supporting the sides of the sack, the sackstool 8 being pivoted at 11 to the frame 9, the descent of the weigh beam 18 and with it the sack stool 8, frame 9 and saddle 12, on correct weight being reached, actuates through an oil brake providing some delay an electrical circuit solenoid which releases a sack-holder clamping the top of the sack. Thereupon the filled sack and sack-stool 8 tilt forwardly about the pivot 11 so that a bellcrank 15 releases the rear depending hook part 17 of the saddle 12 and it falls down clear of the sack under the weight of the latter. The bag therefore drops down vertically, e.g. on to a conveyer belt. A counterweight 25 secured to the saddle then restores it and the locking means to the initial condition. The delay in releasing the sack-holder allows time for the material, e.g. cement, to settle firmly in the sack and this may be vibrated and pre-compressed before supply to the filling tube. An attendant may attend to six or more filling stations and fit fresh sacks on the filling tubes.
